WILLIAM STACY, OF DEVERS, TEXAS.

COLTER.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed July 31, 1909. Serial No. 510,652.

To all whom it may concern:

Be it known that I, WILLIAM STAcY, a citizen of the United States,residing at Devers, in the county of Liberty and State of Texas, haveinvented certain new and useful Improvements in Colters, of which thefollowing is a specification.

My invention relates to new and useful improvements in colters, and moreparticularly to such devices as are designed to be attached to plows,binders, harvesters and other similar implements.

The object of the invention is to provide a device of the characterdescribed which may be attached to a plow beam in advance of the share,and, when so attached, will cut away all tangled and obstructingvegetation as well as cut the sod preparatory to the entrance of theshare.

A further feature resides in the provision of a device of the characterdescribed which will be easily constructed and simple in its operation.

With the above and other objects in view my invention relates to certainnovel features of construction and operation an example of which isgiven in this specification and illustrated in the accompanyingdrawings, wherein Figure 1 is a side elevation of my improved colter.Fig. 2 is a plan view thereof. Fig. 3 is a side elevation of the coltershowing the same attached to the beam of a plow. Fig. 4 is a frontelevation of the device. Fig. 5 is a side elevation of the femalemember. Fig. 6 is a side elevation of the male member.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 refers to the plow beam, which is provided with the usual handles 2and which carries the usual moldboard 3. The plow beam is designed tocarry the colter, as-shown in Fig. 8. This colter includes an arcuatecutting member 4: which carries a rearwardly extending blade 5. Thecutting member is pivotally attached to a downwardly extending supportwhich has a swivel joint intermediate its ends, and is composed of afemale joint member 6 and a male joint member 7, the lower end of themale member operating within the female member. The male member issecured to the plow beam by means of a suitable clamp 8 and projectsdownwardly into a sleeve carried by the extreme upper end of the femalemember. The forward, or free end, of the member 4 is pivoted to arearwardly extending rod 9 which extends through an aperture in an ear10, which is carried by the female member 6. The rear or free end ofthis rod carries a suitable nut 11. Interposed between this nut and theear 10 is a coil spring 12 carried by the rod 9 and operating againstsaid nut and ear and normally holding the blade in contact with theground. This cutting blade 5 is designed to move in advance of the sharepoint and is normally alined therewith, and is provided for the purposeof cutting the vegetation in front of the share as well as for thepurpose of cutting the sod in advance of the share. In case the bladeencounters any obstruction which it is unable to penetrate it iselevated by said obstruction and rides over the same. This elevation ofthe blade causes a forward movement of the free end of the arcuatemember 4 and forces the rod 9 to slide forwardly through car 10 and thespring 12 is thereby compressed. As soon as the obstruction is passedsaid spring 12, operating against nut 11 forces rod 9 rearwardly, andthe movement of said rod has the effect of forcing blade 5 downwardlyand into contact with the vegetation and sod to be cut thereby.

What I claim is 1. A device of the character described comprising asupporting means; a blade support pivotally attached thereto; a cuttercarried by said support and resilient means operating against said bladesupport for holding the cutter yieldably against the obstruction to beremoved thereby.

2. A device of the character described including a rotatable support andmeans for securing the same to an implement frame; a cutting membercarried thereby; a blade carried by said cutting member; a rod securedto the said cutting member and having a slidable resilient connectionwith said sup port whereby said blade is-held yieldably against theobstruction to be cut thereby.

3. In a device of the character described, a cutting member; a bladecarried thereby; a female joint member attached to said cutting memberand carrying a laterally projecting ear; a stay rod attached to said cutting member and projecting through said ear and carrying a resilientmechanism for operating against said rod and ear and thereby operated tohold said blade yieldably against the surface to be cut.

4:. A device of the character described In testimony whereof I havehereto set comprising a supporting means; a blade my hand this the 20thday of July A. D. support attached thereto; a cutter carried 1909.

by said support and resilient means oper- WILLIAM STACY. 5 ating againstsaid blade support for holding In the presence of the cutter yieldablyagainst the obstruction WVM. A. CATHEY,
